Cleaning Chemical Siphon Tube
If you have used the chemical siphon tube you must flush it
with clean water before stopping the engine.
• Place chemical siphon tube filter into a bucket full of
clean water.
• Flush for five minutes.
• Shut off the engine.
IMPORTANT: Simply shutting OFF engine will not
release pressure in the system. When engine has shut
down, squeeze the trigger on the spray gun to relieve
the pressure in the hose.
Nozzle Maintenance
If an adjustable nozzle becomes restricted or clogged with
foreign materials, such as dirt, a pulsing sensation during
use may occur. If pulsing occurs or the nozzle becomes
partially restricted, immediately clean the nozzle with the
kit included with your pressure washer.
To clean the nozzle:
• Shut off the engine and turn off the water supply.
• Detach the nozzle extension from the spray gun.
• Adjust the nozzle extension to the stream position.
• Remove nozzle from the end of the nozzle extension
(Figure 17) using a 2mm or 5/64 allen wrench (included
in the kit).
